Visiting the leaning tower of Pisa: The leaning tower of Pisa

After 7 years, engineers announced the tower stable saying that it stopped leaning in the first time in history and would be stable for at least 200 years. Later, the tower was reopened to the publics on Decemand was declared stable for at least another 300 years. Due to these efforts the tower was straightened by 45 centimeters returning to its 1838 position. The later chosen solution later to prevent the toppling of the tower was to slightly straighten it to a safer position through removing 38 cubic meters of soil from underneath the raised side, they are estimated to weigh 77 metric tons. The authorities ordered the apartments and houses in the path of the tower vacated for safety reasons. The leaning tower of PisaĪs ideas continued to pour, the leaning tower was closed to the public on January 7, 1990.The bells were removed to relieve some weight, and cables were cinched around the third story. They found that the tilt was increasing and many methods were proposed to stabilize the tower, including adding 800 tons of lead to the raised end of the base. On February 27, 1964, the Italian government requested aid in preventing the tower from toppling so a multinational task force of engineers, mathematicians, and historians gathered started to discuss stabilization methods. Another, which was quite helpful in stabilizing the tower, was injecting the foundations with cement grouting in the 1920s. One was taking it apart stone by stone and rebuilding it at a different location. There were numerous trials to set the Tower straight or at least to keep it from falling. The tower was originally designed to be at height of 60 meters but it is currently at 56.67m at the highest side and 55,86m at the lowest side.Įfforts to reposition it straight: The leaning tower of Pisa

It just kept leaning more and more as the weight of the extra floors caused the building to sink further and lean more. Its engineers tried to correct this by making the remaining stories shorter on the uphill side but in vain. The lean was first noticed in 1178 when 3 of the 8 stories were already built due to laying the foundation stones on soft ground of clay, fine sand and shells. The Leaning Tower of Pisa was designed to be straight but today it leans more than five meters off perpendicular. The lean and the story behind it: The leaning tower of Pisa
